I HATE plastic shower stalls and put in steel tubs with tiled surrounds. 

Start to see what makes one more than the other you might have one site looking at quartz counter tops with huge living rooms and the other looking at plastic counter tops,  being able to identify this will help you identify where your property could sit.  

We did a 100% gut/rehab on a 1950's house in 2018 and converted it to a duplex, turned out beautiful, salvaged the original wood floors in parts of the house, put good LVP in the rest, simple plastic mini blinds on every window.

We have a Pottery Barn table at our personal house and we would not buy it again knowing what we know.There was a lady I know that got bedroom furniture that was made out of plastic material and looked good.

Using 18 inch plastic water pipe cut along one side length ways. 

A drain pan is a $50, maybe $100 piece of plastic that should have already been there unless they cracked it trying to install their washer. 

I buy a underground lawn sprinkler head , buy the key in a plastic bag with some oil and bury it someplace easy to find . 

People have told me they have bought a plastic tub to put on the counter in order to do their dishes.

When you do ceilings you only have to paper/ plastic the light fixtures and maybe some smoke alarms, you can hang plastic over windows, but the paint is usually dry before it hits them and wipes off easily.

Lowes used to have some nice material, but then they cheapened it and it looks more like plastic again (it used to have a faux wood grain).
